BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a universal, portable, foldable chair. More specifically, the present invention concerns to a universal heavy duty, light weight, portable, foldable chair which consists of a frame, frame stabilizers, seat, and a locking mechanism to: hold the frame sturdy while in use, keep the chair compacted when in the folded position, and to harness the chair during storage or when being carried.

2. Description of the Prior Art

In many household, commercial, leisure, and military settings it is desirable to have a portable, foldable, heavy duty, light weight chair. It is known in the art to create a chair that can be easily carried and stored. Furthermore it is known that a sturdy comfortable yet compact chair is useful and convenient. Additionally it is known in the art to design a portable chair which is strong enough to hold, for example, at least a 200 pound person. However, these prior art folding chairs are problematic for overweight persons. Further more the prior art is not durable for long time use by overweight or military personal. The reason being these category of people have either a heavy weighing body or are carrying heavy equipment on there clothing in which the chair can not withstand for excessive use and pressure. Additionally prior art foldable portable chairs are relatively bulky and heavy if they are intended for use by a person who is over 200 pounds, requiring undesirable amounts of storage space and/or creating a difficulty when being carried.

BRIEF SUMMARY OF THE INVENTION

A universal heavy duty, light weight, portable, foldable chair is very useful at home or on trips. In this specification a universal heavy duty, light weight, portable, foldable chair is called “a foldable chair” hereinafter. Some other uses for a foldable chair, but not limited to, are: fishing, camping, sporting events, children gatherings, for emergency personal such as paramedics for people in stress that must sit down, and for army and related fields. A folding chair can also be used as a leg rest or small table. Furthermore, a folding chair so compact can be easily put into a persons pocket or handbag. A foldable chair is usually assembled with a chair frame made of bent steel rods, hinge at the center, cloth frame stabilizers, and a seat cloth thereon. Of course the chair frame can be made of various materials including but not limited to hollow steel rods, plastic hollow and solid rods. The hinge which holds the four piece frame assembly intact and allows for the chair to be folded can be made of hollow steel. Of course the hinge can also be made of plastic hollow or solid as well as a solid piece of steel. The seat cloth and frame stabilizers are made of a woven fabric with sufficient strength. Of course the seat cloth and frame stabilizers can also be made of various materials as well. The locking mechanism can be of any type and material but allow for easy locking and unlocking.

Conventional folding chairs are not designed to hold as much weight in comparison with its own size and weight as this folding chair can. For example a prototype of this folding chair was tested. The prototype was 11.5 inches high by 11.5 inches long and 6 inches wide, the chair held up a person weighing approximately 400 pounds. This shows the stability and capacity of the chair, even of the small prototype. Furthermore, conventional folding chairs do not fold into such a compact size in comparison with its own size and weight when at the unfolded usable position as this chair does. The proto type mentioned before was also measured when folded. The measurement when folded is as follows: 8 inches by 6 inches by 1 inch. Furthermore the chair can be carried in a persons pocket or handbag with no discomfort or waste of space.

Accordingly, there exists a need for a universal heavy duty, light weight, portable, foldable chair which can be used conveniently and conventionally. Furthermore, a folding chair which will be easily carried and stored.

DETAILED DESCRIPTION OF THE PREFERED EMBODIMENTS

A universal heavy duty, light weight, portable, foldable chair according to the present disclosure comprises a frame 1 comprising four shaped supports 11 a, 12 a, 13 a, 14 a held together and in position at the center by a hollowed cylinder hinge 15 a. The hinge allows the four frame parts to rotate freely when the chair is unlocked and is to be folded or opened. The seat comprises of two cloths 16 a and 16 b. The seat cloths are made of a strong fabric preferably canvas or oxford cloth. At both ends of the seat cloths it is folded and connected to itself to form a loop 17 a, 17 b, 17 c, 17 d where the flame rods 11 a and 12 a will be received. There exists one piece of cloth 18 a and 18 b at each side of the chair. One end of each cloth 18 a and 18 b is folded and connected to itself to form a loop 19 a and 19 b where the frame rods 11 a and 12 a will be received. The other ends of the cloths 18 a and 18 b will be cut strait 19 c and 19 d. At the bottom of the chair where the two frame rods 13 a and 14 a have an indented section 20 a and 20 b there will be a two piece cloth assembly 22 a and 22 b to connect the cloth bands 18 a and 18 b to 21 a and 21 b. Cloth 21 a will be connected to the two piece cloth assembly 22 a at one end and have a locking mechanism 23 a at the other to lock with one end of 21 b. The locking mechanisms should preferably be one which will allow a strong hold yet be easily unlocked to allow for folding of the chair. For example a hook and eyelet mechanism can be used. Cloth 21 b will be connected to the two piece cloth assembly 22 b at one end and have a corresponding locking mechanism 23 b to fit the mechanism 23 a at the end of the cloth 21 a.
